Abstract: An inverter apparatus for driving a motor M1 comprises switch means 23, 26 for switching between a first control mode for selectively controlling output frequency F and output voltage and a second control mode for obtaining V/F constant control in accordance with a characteristic of the motor. The inverter apparatus and a transport system using the same has a pair of current detectors 6, 7 for detecting output currents of at least two converters 2, 4 for converting detected currents to two phases of output currents of three phases and a pair of axes extending perpendicularly to each other, which are rotated in synchronism with output frequency of the inverter apparatus by an orthogonal projection. A computer 16 such as a microprocessor is provided for adding frequency correcting set frequency with respect to output voltage and the set frequency set from the outside, in accordance with current converted to the two axes, and for deciding predetermined output voltage and output frequency by the set frequency regardless of the current. Switches 19, 20 provide ON/OFF control from the outside. The switches 19 and 20 are electromagnetic switches actuated by push buttons A, B. Push button A switches to variable voltage/frequency for motor 5 and push button B switches to V/F constant for motor M2. The inverter apparatus may be used in a moving carriage (Fig 4) having wheels driven by a motor 31,a motor 33 moving the carriage up and down and a fork for holding baggage being moved back and forth by a motor 36. <IMAGE>

Title: Process for fabricating a semiconductor device
Inventor: YAMAMOTO TOYOJI
IPC: H01L21/8238
Filed: 1996-03-22
Abstract: A process for fabricating a semiconductor device e.g. a CMOS device having a gate structure doped through diffusion from a refractory metal silicide into polysilicon using a lamination of a tungsten silicide layer (25a) and a non-doped polysilicon layer (24a) as a mask, a dopant impurity is ion implanted into a semiconductor substrate (21a) so as to form impurity regions (28a/28b) and dope the tungsten silicide layer (25a) with the dopant impurity, and the dopant impurity is diffused from the tungsten silicide layer (25c) into the non-doped polysilicon layer (24a) during the activation of the dopant impurity introduced into the substrate (21a), thereby making the process simple.
Patent GB-2301669-A (GB)
Title: Angular rate sensor misalignment correction
Inventor: HULSING II RAND H
IPC: G01C19/56
Filed: 1996-05-20
Abstract: An angular rate sensor 20 includes a plurality of spaced apart vibrating beams, for example, four beams, defining a pair of outer beams 22, 26 and a pair of inner beams 24, 28. Each outer beam is mechanically coupled to an inner beam by way of an interconnecting member 30, 32. The outer beams are excited to cause them to vibrate in the plane of the beams and 180 degrees out of phase with the inner beams. In order to compensate for bias errors due to geometric mismatches between the beams, electrode patterns (72, 74, fig 3; 78, 80 fig 4; figs 5, 7-10) are deposited on the beams up to the points of inflection (52, 54, fig 4) of the beams during vibration. The electrodes enable an electric field to be applied either parallel or normal to the longitudinal axis of the beams, which, in turn, cause the beams to twist about their longitudinal axis. Such twisting forces the quadrature acceleration components to cancel and thus electrically compensates for such bias errors due to quadrature acceleration components.

Title: Communications system
Inventor: SMITHERS COLIN RICHARD
IPC: H04B7/26
Filed: 1996-09-18
Abstract: A point to multipoint two-way communications system in which a base station transmits to a remote station ("outstation") on a frequency derived by the base station from the frequency of a previous transmission received by said base station from said outstation. The outstation preferably transmits an FSK modulated data signal to the base station wherein, following reception of this signal, the channel is divided into a plurality of narrow frequency bands and the presence of data signals in each of these bands is detected. The detected signals are then demodulated by at least one narrow band filter centred on the detected status signal frequency bands and the data therein is extracted. Having ascertained the outstation's transmission frequency, the base station is then able to determine an associated transmission frequency for the downlink. Enables low power, low tolerance components to be used in outstation.
